Question:

I'm getting a system code error of sy ce that is a system communication error. I've looked it up and it tells me it could be the controller board located at the bottom of the fridge. I have restarted the unit and alarm cam clear and ran fine for a couple days but now it's in again. The relay clicks on and off on the controller board do u think it's the starter capacitor or the board?

Answer:

Hi Robert,
That is a great question. The Frigidaire refrigerator Error Code SY CE: Communication error during powering up. – This error indicates a problem with wiring to and from the main control board and the user interface board. – Error can also mean the main control board or user interface board (display board) is defective or faulty. To verify what part may be causing the issue you may use an Ohms/Multi-meter to check the continuity of the parts. I hope this helps. Thank you and a have a great day!

Question:

The temp on my fridge and freezer went up to 32 on freezer and 60 on the fridge side. This lasted for 3 days then it went back to normal. I thought it might be the control panel but not sure.

Answer:

Hi James,
Thank you for the great question. We recommend starting with the Defrost Thermostat Kit. It is pretty common with previous customers when the temperature would rise. If you are not able to test the thermostat with a multi meter it is a pretty in expensive part and might be worth installing a new one to see if it fixes the issue.
Hope this helps!

Chest freezer hasn't been used in a couple years. Plug it in and hear a soft hum but doesn't cool. Compressor not kicking on? Thanks

Bill

Answer:

Hello Bill, thank you for contacting us. It does sounds like the compressor is not coming on, it may need a new start relay or run capacitor. You can test these with a multi-meter to determine which is at fault. Hope this help!

Question:

Not sure how to test run capacitor and start relay

William
for model number

Answer:

Hi William,
Thank you for your inquiry. You can test both of those parts with a multi-meter. Make sure after unplugging your capacitor you release any electrical charge. You can do this with a screwdriver that has an insulated handle. When testing your capacitor set your meter to 1000 ohms. If your meter stays on 0 then your capacitor needs to be replaced. For your start relay, set your meter to the lowest setting and calibrate it to 0. Your relay should be reading anywhere between 10 - 100 ohms. If it does not, then it is likely broken and needs to be replace. I hope that helps. Good luck with your repair.

Answer:

Hi Rodney,
Thank you for your inquiry. There are a couple of parts that you should probably test with a multi-meter to see if they are causing your problem. This part being the first. I would also test the defrost thermostat as well. Good luck with your repair!

The controller (current relay) burned up

1. Unhooked a retaining wire that secures the controller to the compressor terminal box. 2. removed destroyed part. 3. Got the model and serial numbers and got online. 4. Ordered part 5. Waited a couple of weeks to get part 6. Found that the manufacturer had daisy chained a bunch of components together with some funny deep socket plugs that by themselves are not routinely found so rather than buy a laundry list of unnecessary parts to get the aforementioned plus and make my customer wait a couple of more weeks I chose to connect the wires to a couple of high temperature female stainless steel quick connectors and feed the wires directly into the controller. Fortunately the controller had the polarity marked on the housing. (L for Line was the hot lead and C was for common the neutral lead) Failure to follow proper polarity will damage the part and could kill the compressors's start wimding.

Rear of upper shelf would freeze, while the rest of the freezer was dripping wet

We opened our freezer last week only to find the bottom 2/3 was barely cold, while only the rear of the upper shelf was cold. In fact, it was covered in frost, despite being a frost-free model. Our frozen veggies were slushy, not rock hard, and our frozen juices were all liquid. We defrosted the freezer, plugged it back in, but immediately noticed that we didn't hear the 'whhoooooosh' that you typically hear when you close the freezer door. After 30 minutes, the rear upper shelf was frosty again, but the rest was still at room temp. We figured the freezer was a goner, so we started looking at new freezers. I headed online to see if I could fix it, and I eventually found this site. I had learned online that these symptoms can be caused by either a bad capacitor, or a bad controller (which the capacitor plugs in to). I guess you can't necessarily tell which of the two parts is defective, so I chose to order/replace both of them. I ordered the correct parts from partselect.com, and they alerted me that Frigidaire has a new replacement part for the capacitor. When the parts arrived (quickly, ftw!), I unplugged the freezer and snipped the two wires leading to the controller. Next I unplugged the controller from the compressor housing. I spliced the replacement controller's wires into the freezer's wires (using my own wire nuts...as none were included with my order :( ). I snapped the new controller onto the compressor mounting, and then plugged the capacitor in. I plugged the freezer back in, and it was time for the moment of truth. The interior light of the freezer came on, and I could hear the compressor 'humming'. I could hear it humming before the repair, so the big test was to see if it got cold. I was nervous because the freezer DIDN'T make the 'whoooshing' noise right away, but after just an hour, the 'test' mug of water was already turning into ice. It was fixed!!!! If you have these symptoms, you CAN do this!!! Unplug the freezer. Cut two wires. Unplug the controller. Splice two wires. Plug in the new controller. Snap in the new capacitor. DONE!!!

Extreme noise for 3 months, then not cold

Pulled the fridge from encloser, removed rear cardboard cover and found compressor in rear. The compressor, being very accessable, was easy to find the bad starter/capacitor. I removed the spring retainer, pulled the capacitor off the starter, removed the starter by pulling outward and replaced with new. All went well when the unit started and cooled as new. Some noise at times, but traced to icemaker. As time went by, that noise was gone.

Fridgerator shorted out. Smoke coming from back.

There was an accidental spill which seeped through the water-hose feed hole in the bottom of the fridge. The liquid had dripped down onto the Starter and Run Capacitor and shorted them out. I called an applicance repair shop to possibly get it fixed. They estimated around $500 with the service call, parts and labor. Not a chance was they getting that from me. So I unhooked the retaining wired and removed the burnt parts. I then looked up the part numbers and ordered the 2 parts I needed from Parts Select for $50 bucks including shipping. In just two days my order arrived. I installed the 2 parts the same way and as easily as I took them out. Now my fridge is running good as new. When my HUSBAND returned home from work he was stunned to see that I had done the repair without his help. He laughed and said, "Yep. You da' woman!"

Refrigerator was not cooling

This was a simple job. Raised the flap in the back that houses the compressor, removed the wire that holds the relay, pulled out the old relay and pushed the new one on. Replaced wire holder and that was it. Plugged it frig and freezer is at zero and lower compartment at 35. As easy as brushing your teeth!

Refrigerator quit running

I located the part that was the culprit as it had buzzed very much before quitting. This is an easy removal as the part is in a two prong jack and just needs to be carefully removed with the new part inserted back in the jack provided. The refrigerator works fine now, but the run capacitor will still buzz on start up of the compressor. I do hope this is normal in this model? anyway it runs fine mow. Thank you.

Freezer and refrigerator stopped cooling

The site offers a video for this part which worked perfectly. In addition to replacing the part, since the cardboard panel was off, we also cleaned all the dust off of the coils which someone recommended to do annually.
